I've never really used the headset much while using the 360 controller on pc, not being much into the games that use voice communications and junk. But I've read that some games, like the newest FS game puts stuff like radio on to the headset. But only games that are made with the 360 controller in mind or with a patch to support it do this. So I figure halo2 and some other new games will. And no, not all the sounds will come out if you use it.
